A novel reusable and efficient nano-ZnS catalyst for green synthesis of xanthenes and its derivatives under solvent free conditions

Abstract

A novel reusable and efficient nano-ZnS catalyst was prepared by a single pot wet chemical method and analyzed by SEM, XRD, FTIR and TEM techniques. We have studied the solvent effect, recyclability and reactions of various aromatic aldehydes with dimidone and β-naphthol for the synthesis of 1,8-dioxo-octahydroxanthenes and aryl-14H-dibenzo [a,j] xanthenes using ZnS nano particles as the catalyst under solvent free conditions without using any acidic catalyst or toxic materials. These results show that nano-ZnS is a potential catalyst for the development of green synthesis in the preparation of xanthenes and that the reaction proved to be economical which is of utmost importance for industrial applications.
